US Airways has been pretty loyal to the Styrofoam coffee cups in first class on short-flights and pre-departure.
The Styrofoam cups have been pretty dangerous. I’ve cracked the Styrofoam a little bit occasionally and I’ve been scared of tipping over the light-weight cups.
On my last flight, I got a coffee before my flight and they gave me coffee in a paper cup. Sorta like Starbucks. Sorta like this without the lid:
It was sturdy. It didn’t crack. And I didn’t feel like I was going to pour my drink all over myself. This paired with US Airways offering real glassware on their shorter flights too has made me a very happy flyer.
